You know a funny thought I had for the M3 Lee/Grant is what if a M3 was modified with the horizontal spring boggie suspension and the wider tracks that go with it, and the strongest engine that was put in the latest model Sherman's, and has the hull 75mm cannon replaced with the 76mm cannon and a 2-pdr installed in the turret, that's my odd thought.
This tank would be operated by either 6 or 7 guys who are all best friends since they were kids and in this M3 they are unstoppable
